TRIP MECHANISM FOR BUNDLE-CARRIERS.

ineaove.

To 0 whom it may concern:

Be it known that I, JOSEPH BAXTER, a citizen of the United States, and a resident of Moscow, in the county of Latah and State of Idaho, have invented a new and Improved Trip Mechanism for Bundle-Carriers, of which the following is a full, clear, and exact. description.

Among the principal objects which the present invention has in view are: to provide means for stopping the delivery of bundles or sheaves from a carrier; to provide means for manually releasing the bundles for delivery; and to simplify the mechanism for effecting the operations above outlined.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views, and in which liigure 1 is a side view of a carrier constructed and arranged in accordance with the present invention; Fig. 2 is a top plan view of the same; Fig. 3 is a detail view, on an enlarged scale, showing in perspective the locking means for the tail-gate with which the carrier is provided.

The frame of the carrier shown in the accompanying drawings is of conventional design, having side rails 8 and cross braces 9 and 10. The frame is reinforced by tie-rods 11. and is provided at the outer end with a roller 12. The tail-gate employed at the delivery end of the carrier frame is composed of a plurality of cross bars 13, which are rigidly mounted in the vertical extensions 14 of swinging arms 15. The arms 15 are provided with a horizontal extension, which is rigidly mounted upon a shaft 16, and is provided with a cross head 17, said cross head having a vertical extension, and projecting at opposite sides of the shaft 16. The shaft 16 is mounted in suitable bearings provided in the side rails 8. The tailgate is held in operative position, suchas shown in Fig. 1 of the drawings, by a latch bar 18. The latch bar 18, as shown best in Fig. 3 of the drawings, is cut away to form a square shoulder 19 to engage a block 20, which is set between one of the rails 8 and a band loop 21. The band loop 21 is rigidly mounted upon the rail 8, and is braced by a bar 22 secured to said band loop by a fastening 23, and to a bracket plate 24,

which is likewise rigidly mounted upon the rail 8.

The latch bar 18 is pivotally connected by means of a pin 25 to the lower extension of the cross head 17. .Vhen the vertical extensions 14 of the tail-gate are raised above the upper edges of the rails 8, and the cross head 17 is in vertical position, the bar 18 is drawn toward the outer end of the rail sufficiently to permit the shoulder 19 of the latch bar to drop in the path of the block 20, to thereafter operate to prevent the rocking of the tail-gate on its pivot. The tail-gate is raised, and the latch bar 18 is drawn to holding position by means of a spiral spring 26. The spring 26 is connected by a wire 27 to the cross head 17, said wire being passed through a perforation 28 formed in the upper projection of said cross head (see Fig. 3 of the drawings). The opposite end ofthe spring 26 is secured to a screw rod 29, which loosely extends through a perforation formed in the ear 30 of the bracket plate 24. A nut 31 is provided for the screw rod 29, the manipulation of which serves to vary the initial tension on the spring 26. At all times, the tension on the spring 26 is suflicient to turn the tail-gate and parts connected therewith to the receiving position of said gate.

The means for tripping the gate and the latch bar 18 thereof is connected with a pull rod 32. crating station of the attendant on the binder. The rod 32 is connected with a lever arm 33, which arm is pivoted at 34 conveniently upon, at the under side of, the cross brace 10. Intermediate the end of the lever 33 and the pivot 34, the lever is provided with perforations 35 and 3G. perforations 35 and 36 are spaced apart, as

shown best in Fi 2 of the drawin s. to arovide for an increased movement of a wire 37, and a relatively diminished movement of a wire 38. The wire 37 is directly connected with an arm 39 set out from a. trip 40, the object whereof is to lift the latch bar 18. To this end, the trip 40 is pivoted at 41 upon the end of a horizontal extension 42 of the band loop 21. At the free end of the trip 40, it is provided with a yoke, the arms 43 whereof infold the latch 18 and are provided with a roller 44, suitably mounted in bearings in the arms 43. The wire 38 is directly connected to the lower end of the The rod 32 is extended to the op- The cross head 17, as seen best in Fig. 3 of the drawings.

Being provided with a carrier constructed and arranged in accordance with the present invention, a binder delivers thereto bundles or sheaves, which are held from leaving the carrier by the tail-gate above described, this being normally locked by the latch bar 18. hen now, in the opinion of the attendant, a sutiicient number of sheaves have accumulated on the carrier, he empties the same by pnlling on the rod 82 to move the lever arm 33. The lever arm 33, in moving, first operates by means of the wire 37 upon the trip 10 to draw the same back, the roller d4- passing under the latch bar 18 to lift the same, until the shoulder 19 thereof clears the block 20. Coincident with the lifting of the shoulder 19 from engagement with the block 20, the wire 88 is drawn upon to rock the cross head 1'? to depress the vertical extensions 1% and cross bars 13 of the tail-gate from the path of the sheaves. The operator continuing to hold the rod 32, the accumulated sheaves are delivered from the carrier. The delivery having been accomplished, the operator, releasing the rod 32, permits the spring 26 to rock the cross head 17 to initial position, lifting thereby the extensions let and the cross bars 13 into the path of succeeding sheaves, and coincidentally moving the latch bar 18 over the block 20 until the shoulder 19 of said bar engages said block. The carrier is then in position to prevent the delivery of succeedin sheaves until accumulation on the carrier is sutlicient to be again delivered.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination with a bundle carrier, of a pivoted and spring-pressed tail piece at the delivery end of the carrier, a pivoted latch for holding the tail piece in receiving position, a pivoted member engaging the latch and adapted to release the same, and means connected with the said pivoted menr ber for operating it from a distance.

2. The con'ibination with a bundle carrier, of a pivoted and springpressed tail piece at the delivery end of the carrier, a latch for holding the tail piece in receiving position, a trip for the latch, a pull rod, and n'ieans connecting the pull rod with the trip and tail piece whereby the latch will be re leased in advance of the movement of the tail piece.

3. The combination with a bundle carrier, of a tailpiece pivotally mounted on said carrier and having a vertical extension pro truding above said carrier to prevent bundles from passing therefrom; a cross head rigidly mounted on said tailpiece; a spiral spring operat-ivcly connecting said cross head and said carrier, to move said tailpiece into operative position; a swinging latch pivotally connected to said cross head at the side of the pivot thereof opposite that to which said spring is connected; astop mounted on said carrier to hold said latch and tailpiece connected therewith in position to maintain the vertical extension above said carrier; a trip operable to release said latch; and means operable from a distance to control said trip.

The combination with a bundle carrier,

of a tailpiece pivotally mounted at the do livery end of said carrier, said tailpiece having verti .al extensions and cross bars connectcd therewith, normally above the upper edge of said carrier; a spring operatively connecting said carrier and said tailpiece to normally lift the same to oporatim position; a pull-rod ope able from a distance to depress said tailpiece out of operative position; a swinging latch o nn-atively connecting said tailpiece and said carrier to prevent the dislodgment of said. tailpiece from the path of said bundles; a trip for said latch; and means connecting said trip and said pull-rod to move said trip at a greater rate of speed than said. tailpiece, to release said latch in advance of the movement of said tailpiece.

5. The combination with a bundle carrier, of a pivoted and spring-pressed tail piece at the delivery end of the carrier, a latch for holding the tail piece in receiving position, a trip for the latch, a pivoted lover, a wire connecting the lever with the tail piece, a. wire connecting the lever with the trip, the last named wire being connected with the lever at a greater distance from the pivot. of said lever than the first wire, and means for operating said lever.

(l. The combination with a bundle :arrier. of a tail piece pivoted to the delivery end of the carrier, said tail piece comprising arms having vertical extensions connected by cross bars one of the arms being provided with a cross head, a spring connected with the cross head and carrier, a stop mounted on the carrier, a. latch pivoted to the cross head and engaging said stop, a forked trip pivot-ally mounted on the carrier and between the members of which the latch works, and means connected with the trip for swinging it to release the latch from the stop,

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
